The pilot whale is a species of oceanic dolphin that is commonly found in the North Atlantic and other parts of the world. Synonyms for the pilot whale include blackfish, pothead whale, and ca'ing whale. The name blackfish comes from the dark coloration of their skin, while pothead whale refers to the bulbous shape of their forehead. Ca'ing whale is a term used in the Caribbean to describe these creatures, and is believed to have originated from the sound they make when they exhale through their blowholes. Despite their name and close resemblance to whales, pilot whales are actually a type of dolphin and are known for their highly social behavior and intelligence.
